D) screw I am pretty sure
Suppose the Gas is acting ideally, Then, According to Ideal Gas Equation;
P₁ V₁ = P₂ V₂ ----- (1)
Data Given:
P₁ = 885 torr
V₁ = 125 cm³
P₂ = 225 torr
V₂ = ?
Puting values in eq, 1;
V₂ = P₁ V₁ / P₂
V₂ = (885 torr × 125 cm³) ÷ 225 torr
V₂ = 491.66 cm³
Reaction sequence:
2c(s) + o2(g) -> 2co(g)
fe3o4(s) + 4co(g) -> 3fe(l) + 4co2(g)
According to first equation, 2 moles of carbon produce 2
moles of carbon monoxide. So 1 mole of carbon will produce 1 mol of carbon
monoxide (the same number).
According to the second equation, 4 moles of carbon monoxide
produce 3 moles of iron. We should make the cross multiplication with those
numbers:
4 moles CO/3 moles iron = 1 mol CO/x
x = 1 mol CO*3 moles iron/4 moles CO = 0.75 moles of iron
You did not specify the types, but I believe the answer would be gamma radiation.
Answer:
v = 46.5 m/s
Explanation:
Given data:
Mass of car = 1210 kg
Momentum of car = 56250 kg m/s
Velocity of car = ?
Solution:
Formula:
p = mv
p = momentum
m = mass
v = velocity
Now we will put values in formula:
56250 kg m/s = 1210 kg × v
v = 56250 kg m/s / 1210 kg
v = 46.5 m/s
So a car having mass of 1210 kg with momentum 56250 kg m/s having 46.5 m/s velocity.
